Is this switch quiet? I bought a Cisco switch that is similar, but it as loud as a bathroom fan... even inside a closet.

I just bought this switch from a vendor and it is pretty quiet to have in a home office environment. Great switch!

Not fanless. I could be wrong, but I don't believe there are fanless PoE switches with these many ports. The power output warrants cooling. With that said, this is a fairly quiet switch--not silent but not noisy either.

It is REALLY noisy, seriously I will be returning mine because of that. I had bought for my bedroom but this is unbearable, even the lowest speed generates so much more noise than my old AC on the max speed.

I have a Honeywell in my bedroom (new touch screen) and it's very loud. These are quieter. But I can still hear them when I'm across the room on the couch. Hope that helps

No..the unit is quieter than my dishwasher or even the fridge when the comoressor is running. Id say equal to a small desk fan. I cannot hear it unless im in the kitchen.

No sound. It's only a switch panel and resistance matcher. What your doing May be possible. But we don't use it that way.

It's not very loud. I sleep with the ceiling fan on and this thing too, and sometimes I can't tell if it's on. The fan is basically what you would find in a computer tower so the noise is minimal. A slight humm if anything

I don't find it noisy at all and there are 12 LED's in it. Easy install, I love mine. Hope that helps.

It's a mechanical relay and makes a click, but it is not very loud. There are ssr "relays" available. Make sure to use a good heat sink if you need to switch any real current.

No, and no. It is very quiet. But this is a very small fan. It moves a nice amount of air for being so small. I needed one that would fit in a recess in the ceiling. It is perfect for where I needed to put it. I have this mounted where an old light fixture was. So, the old light switch is still there, though I don't usually use it. This switch should not affect whether or not it makes any noise. Only negatives: The light is NOT dimmable, and the housing is too small to insert a remote control. All my other fans are on remotes, which is very convenient

One other comment to add. I read where one person said it was loud. Mine is relatively quiet...much quieter than an up right.

I don't think it's loud at all. I've had it running 24/7 in my bedroom since I got it and it's pretty quiet. It's about the same noise as a window a/c or quieter. Hope that helps!

I call it quiet, even under load. I still hear fans, but they don't overwhelm my tiny speaker system. If you want zero noise, then this won't work.

I have had this installed for 6 months now. It is typically used with a variable speed control in place of an on/off switch. It is an industrial strength fan. When it is running at full speed it is moving a lot of air, making it necessary to raise your voice a bit to talk over the noise. But it really airs out the room in a hurry. At low speeds, it is much quieter. The air noise is just a whisper, but there is still a noticeable hum from the motor.

The SG300-28P (PoE) has 2 fans. I have 2 servers and a Synology NAS with 5 hard drives in a closet and it's almost silent. The fans in this switch are the loudest things in the closet. Thinking about returning mine for the non-poe version without fans.

I know this is an old question but I just bought and installed this switch. I was worried (because of this question) about the switch buzzing. I have this hooked up to control 4 Cree 65W equivalent BR30 dimmable LED lights and notice no buzzing sound what so ever. Even at the lowest setting with my ear on the switch, I hear no buzzing.

I hardwired the wall switch to be "ON" all of the time. The only problem is that the humidity sensor sometimes starts the fan in response to changes in the room air even when the shower is not in use. Darn kids!
